WILDLIFE SANCTUARY(Suaka Margasatwa/SM) is a sanctuary reserve area characterized by its biodiversity and/or an area of unique fauna need to be maintained to let the unique fauna sustain.

The criteria of appointment and establishment of wildlife sanctuary:a.Habitat and breeding site of animal species that need to be conserve;b.Habitat of rare and or endangered species;c.Has a high diversity and animal population;d.Is a habitat of certain migratory species; and ore.Has enough area as the habitat of the related fauna.

According to its function, wildlife sanctuary could be utilized for:a.Research and development;b.Science;c.Education;d.Limited nature tourism; ande.Cultural activity.

The body colouration is unmistakable: the front part of the body (ending just after front legs) and hind legs are black, while the back has a saddle of grizzled white or grey. While this colouration seems conspicuous, it renders the tapir nearly invisible in the moonlit jungle at night. Young animals are completely different from their mature relatives, resembling brown watermelons with whitish stripes and spots on a chocolate brown coat. They lose this baby coat 4-7 months after birth. The thick hide is sparsely covered with hair, and there is no mane or ridge on the neck. The body is round and barrel-shaped, the tail is no more than a stump. The nose and upper lip are extended to form a short, prehensile proboscis. The eyes are small and beady, and the ears are rimmed with white.

Ecology and Behavior

Malayan tapirs are primarily - although not exclusively - nocturnal. They cover large distances in their search for food, making frequent stops to eat. Regularly used paths are used in these foraging excursions, and several may lead to bodies of water. Each animal occupies a large territory which overlaps that of its neighbours. These paths and territories are marked with urine, which is sprayed on small bushes and plants. When moving, the Malayan tapir walks slowly with its head down, which probably allows it to pick up the scents of other tapirs. Individuals also communicate with shrill whistles. The Malayan tapir is a good climber, scaling steep slopes with relative ease, and when alarmed gallops off with surprising speed.

Tapirus is a Latinized corruption of tapyra - the Tupi name for the tapir (the Tupis are an aboriginal tribe from the Amazon). Indicus (Latin) of India: this name is misleading as this ungulate does not live in India, and was probably meant to refer to the East Indies (Malay Peninsula). Due to its larger size, different range, and unique colouration, this tapir is sometimes placed in the genus Acrocodia.

The second half of the 20th century was truly a golden age for astronomy. Rapid advances in technology made it possible to build very large optical telescopes on the ground. By the early 21st century astronomers were using about a dozen telescopes with mirrors larger than 8 m (300 in) in diameter. Because it is much cheaper to build telescopes on the ground than in space, large ground-based telescopes with their ability to gather large amounts of light (think of a telescope as a bucket for collecting light; the bigger the bucket, the more light collected) are particularly valuable for studying the faintest objects. The most distant objects tend to be very faint, but they are very important for understanding the evolution of the universe. Since light takes a long time to reach us, the universe gives us a kind of time machine so that we can see what it was like when it was much younger than it is now. For the most distant objects observed so far, it took nearly 13 billion years for their light to reach Earth, so we are seeing them as they existed 13 billion years ago.

History of Astronomy, history of the science that studies all the celestial bodies in the universe. Astronomy includes the study of planets and their satellites, comets and meteors, stars and interstellar matter, star systems known as galaxies, and clusters of galaxies. The field of astronomy has developed from simple observations about the movement of the Sun and Moon into sophisticated theories about the nature of the universe.
